Radiation Crosslinked Modified ETFE Insulation Wires and Cable
INSTRUCTION
KH55A wires and cables meet USA Military Standard MIL-W-22759, and China Military Standard GJB773.
This wires & cables are made of ETFE and modified by irradiated cross-linked with excellent dielectric feature, and mechanical strength.
This products can endure high and low temperature( -65°C to 200°C), small size,lightweight,non-shrinkable,cracking-resistant,and-mechanical-performance,chemical-resistant,solvent-resistant,electric arc,UV, hydrolyze-resistance, offer the excellent performance in harsh environments.
The radiation cross-linked modified wire and cable with excellent features, which are widely used as Aero speacecraft wire, astro-airship wire, irradiate-resistant wire, and all kinds of apparatus instrument wire, and they are ideal high quality wires for Aero-spacecraft.
As-per-GJB9001A-2001-and-GB/T19001-2000idtISO9001:2000--<<Quality-Management System Requirement>>,KH55A wire and cables have passed the test of national level institute, all the indexes comply with USA military products standards.
